The effect of fertilizers application in optimization of macronutrients take up by spring rape

Research results on dynamic of macronutrients content in spring rape plants during vegetation depending on different fertilizers rates stated in this article. The macroelements content in plants of spring rape and its take up by plants were researched. The effect of fertilization on these indexes was determined. The increased of fertilizers rates improved macroelements contents in plant and its take up by plants. The nitrogen content in rape seeds was 3.27-3.96 %and this index in straw was 1.73-2.06 %.
